Verify that the operating system meets the file descriptor requirement.

Informatica service processes can use a large number of files. To prevent errors that result from the large number of files and processes, you can change system settings with the limit command if you use a C shell, or the ulimit command if you use a Bash shell.

To get a list of the operating system settings, including the file descriptor limit, run the following command:

C Shell

limit

Bash Shell

ulimit -a

Informatica service processes can use a large number of files. Set the file descriptor limit per process to 16,000 or higher. The recommended limit is 32,000 file descriptors per process.

To change system settings, run the limit or ulimit command with the pertinent flag and value. For example, to set the file descriptor limit, run the following command:

C Shell

limit -h filesize <value>

Bash Shell

ulimit -n <value>
